Some of our judges have purchased badges already (in order to participate in the housing lottery). The others wait until GenCon and just get their Judge's Badge (Locals, and people staying out-of-block).

I assume the possible badge sell-out will not affect judges badges, but i'd love to have that confirmed.

We do have a set amount of GM badges accounted for in our figures. I certainly wouldn't wait until the week before the con to put in your request for GM badges, but put in your request in promptly and you should be fine. We will keep an eye on it and let people know if we're anywhere close to having an issue.
